I'm working with a graphical open-source simulator that browses the name of the fed file, using
_rtia.createFederationExecution(_federationName, fedFile.asFile().toURI().toURL());
When the first federate is launched in the same computer where the rtig is launched, it works perfectly.

But when the rtig is launched in a computer m1 and the 1st federate is launched in a computer m2 (with CERTI_HOST=m1), then the rtig takes as fed name the name with the full-path-address, and it cannot find it in the m1's tree.
I tried lanching rtig in m1 (linux) and 1st federate in m2 (windows) and vice-versa (rtig in m2 and federate in m1).
If I use a c++ federate where the name of the federation and fed file are hard-coded, and launch in the same computer as rtig, it also works.

Federate on windows, rtig on linux:
rtig
